Technical Field

[0001] The utility model relates to the technical field of laser detectors, in particular to a laser detector which is easy to install. Background Art

[0002] Laser intrusion detectors belong to the category of active intrusion detectors, which are mainly composed of laser transmitters and laser receivers. The laser transmitter emits a directional strong laser beam, which forms a warning line with an invisible modulated laser beam (single or multiple beams), and uses the blocking alarm method to close the perimeter, plane and three-dimensional space to form a laser intrusion solution system.

[0003] The laser transmitter and laser receiver in the laser intrusion detector are usually installed symmetrically in the detection area, and the current laser intrusion detector is usually provided with a fixing seat at the bottom, with an assembly hole on the fixing seat, which is installed in conjunction with mounting parts such as screw tops.

[0004] When installing a laser intrusion detector, it is necessary to adjust the positions of the laser transmitter and the laser receiver so that they are relative. During the installation process, sometimes they cannot be directly aligned, and the angle of the entire laser intrusion detector needs to be adjusted, which is cumbersome to operate. Moreover, when the laser transmitter and the laser receiver are not aligned, it is necessary to unscrew the bolts again, adjust them, and then install them, which is time-consuming and laborious.

[0030] In one embodiment, a fixing plate 34 is fixedly disposed on the rotating frame 31, and the fixing plate 34 is slidably connected to the mounting base 2. A locking rod 35 is inserted into the fixing plate 34, and the fixing plate 34 is fixedly connected to the mounting base 2 through the locking rod 35.

[0031] After the two detector bodies 1 are aligned with each other, the locking rod 35 can be screwed inwards so that the locking rod 35 is pressed against the mounting base 2, thereby fixing the rotating frame 31.

[0032] In one embodiment, the lifting mechanism 4 includes an insert plate 41 inserted into the rotating frame 31, and two slide grooves are provided in the insert plate 41, and a slide rod 42 is provided in each of the two slide grooves, and movable rods 43 symmetrical to each other are provided at both ends of the slide rod 42. A movable slider 44 which is rotatably provided on the bottom end of the movable rod 43 and is sleeved on the slide rod 42, and a fixed block 45 which is fixed on the detector body 1 is rotatably provided on the top end of the movable rod 43. A driving mechanism is also provided on the insert plate 41, and the driving mechanism is used to drive the movable slider 44 to slide left and right on the slide rod 42, and the two movable sliders 44 on the same slide rod 42 make opposite movements.
